Just started playing with this today, and have stumbled across an issue.
I have used the Sub D workflow to create some creases in a cloth material I am creating. I have now taken this to nurbs, so that I can project onto it, but the whole surface is split up into sub D squares. Is there anyway to merge / convert back into a single surface I can project on to ? Or will I have to rebuild the geo using contours ? I am unable to use extraisocurve, as this just limits it to the square. Thanks
